K51 is replacing oil and natural gas with computing power – the fuel of the future.Modern data centers are already powered by renewable energy, which reduces CO2 pollution. Nevertheless, we are still faced with the problem of how to deal with waste heat from computers. Air cooling cannot keep it in check efficiently enough and most of the waste heat is released into the atmosphere. Innovative solutions are needed to reduce this energy waste and keep the valuable energy in the cycle.The solution is to run high-performance computing (HPC) where fossil-free heat can be used - for example, in greenhouses, hotels or industrial plants. This allows waste heat to be used elsewhere and kept in circulation in an efficient way. In this way, we use the same energy twice. This makes economic as well as ecological sense.

Industrial guest researcher, data scientist and engineer at the COSMOS DevOps H2020 project.COSMOS is designing and developing novel DevOps methodologies, techniques, and tools that will enable effective, continuous development and evolution of cyber-physical systems.COSMOS addresses challenges in the cyber-physical system maintenance process by realising DevOps pipelines delivering efficient and cost-effective development of trustworthy and secure cyber-physical systems capable of adapting their behavior to dynamic contexts and unexpected operating scenarios. COSMOS technologies will:- Reduce the effort and costs in the development, validation and verification, and evolution activities of cyber-physical systems.- Reduce the cyber-physical system fault proneness to security threats thereby providing increased trustworthiness.- Make cyber-physical systems capable of autonomously adapting (or reacting) to unexpected behavior.These outcomes will be achieved through the development of novel infrastructure and technologies for cyber-physical systems development and deployment.
